Theprimary display panel 162 may be mounted (e.g., fixed, attached) to thefront side of a housing of the electronic display device. Inembodiments, the electronic display device may include a set ofauxiliary display panels that are maintained in a stacked configuration(e.g., layered structure) within a storage compartment of the housing ofthe electronic display device. The set of auxiliary display panels maybe slidably extendable (e.g., configurable to be slid, shifted, orotherwise moved) from the storage compartment within the housing of theelectronic display device to an extended position (e.g., expanded orelongated from the original position). For instance, one or moreauxiliary display panels of the set of auxiliary display panels may bemoved from the storage compartment to an extended position adjacent tothe primary display panel 162 to expand the display size of theelectronic display device. In embodiments, the electronic display devicemay include a display controller for managing presentation/output ofvisual elements to the primary display panel and the set of auxiliarydisplay panels. In certain embodiments, the display controller may beconfigured to detect the current display configuration of the electronicdisplay device, and adjust the display arrangement (e.g., organizationof screen content/visual elements) to be presented on the primarydisplay panel 162 and the set of auxiliary display panels. Aspects ofthe disclosure relate to using one or more auxiliary display panels ofthe set of auxiliary display panels to establish one or more displayconfigurations for the electronic display device.

Aspects of the disclosure relate to an electronic display deviceconfigured to operate in a first display configuration 160. Inembodiments, the first display configuration 160 may correspond to asmart-watch usage mode (e.g., compact form-factor, resource-lightoperating system, wearable design). In embodiments, when in the firstdisplay configuration 160, the electronic display device may beconfigured to maintain the set of auxiliary display panels in anon-active (e.g., off) state within the storage compartment of thehousing, and only use the primary display panel 162 for presentation ofvisual elements on the display of the electronic display device. Incertain embodiments, the display controller may detect that theelectronic display device is in the first display configuration 160, andgenerate a first display arrangement for provision to the primarydisplay panel 162 of the electronic display device. The first displayarrangement may include a set of applications or features of theelectronic display device that are suited for operation with a compactscreen size. As an example, the first display arrangement may includeapplications that are frequently used (e.g., usage frequency above athreshold level), applications that have specialized operation modes(e.g., smart-watch mode), applications that have low resourcerequirements (e.g., screen area, processing resources, memoryresources), or the like. Other methods of configuring the first displayconfiguration 160 are also possible.

Aspects of the disclosure relate to an electronic display deviceconfigured to operate in a second display configuration 170. Inembodiments, the second display configuration 170 may correspond to asmart-phone usage mode (e.g., one-handed usage form-factor, lightweight,pocket-size). In embodiments, when in the second display configuration170, the electronic display device may be configured to utilize one ormore auxiliary display panels of the set of auxiliary display panelsstored in the storage compartment to expand the screen size of theelectronic display device. As an example, three auxiliary display panelsincluding a first auxiliary display panel 172, a second auxiliarydisplay panel 174, and a third auxiliary display panel 176 may beextended from within the storage compartment (e.g., using a set of slidemounts) to positions in the same plane as the primary display panel 162.In embodiments, the three auxiliary display panels may be aligned withthe primary display panel 162 such that the primary display panel 162,the first auxiliary display panel 172, second auxiliary display panel174, and third auxiliary display panel 176 are positioned at the sameheight. In certain embodiments, the three auxiliary display panels maybe connected to the primary display panel 162 via an interlockingmechanism (e.g., magnets, latches, fasteners). In embodiments, thedisplay controller may detect that the electronic display device is inthe second display configuration 170, and generate a second displayarrangement for provision to the primary display panel 162 as well asthe auxiliary display panels used as part of the second displayconfiguration 170 (e.g., the first auxiliary display panel 172, secondauxiliary display panel 174, and third auxiliary display panel 176). Thesecond display arrangement may include a set of applications or featuresof the electronic display device that are suited for operation on amoderate screen size.

Aspects of the disclosure relate to an electronic display deviceconfigured to operate in a third display configuration 180. Inembodiments, the third display configuration 180 may correspond to atablet usage mode (e.g., large screen size, two-handed usage formfactor). In embodiments, when in the third display configuration 180,the electronic display device may be configured to utilize one or moreauxiliary display panels of the set of auxiliary display panels storedin the storage compartment to expand the effective screen size of theelectronic display device. In embodiments, the third displayconfiguration 180 may make use of a greater number of auxiliary displaypanels than the second display configuration 170. As an example, sevenauxiliary display panels including the first auxiliary display panel172, second auxiliary display panel 174, third auxiliary display panel176, fourth auxiliary display panel 182, fifth auxiliary display panel184, sixth auxiliary display panel 186, and seventh auxiliary displaypanel 188 may be extended from within the storage compartment (e.g.,using a set of slide mounts) to positions in the same plane as theprimary display panel 162. As described herein, the seven auxiliarydisplay panels may be aligned to the same height as the primary displaypanel 162, and be connected to the primary display panel 162 via aninterlocking mechanism (e.g., magnets, latches, fasteners). Inembodiments, the display controller may detect that the electronicdisplay device is in the third display configuration 180, and generate athird display arrangement for provision to the primary display panel 162as well as the auxiliary display panels used as part of the thirddisplay configuration 180 (e.g., the first auxiliary display panel 172,second auxiliary display panel 174, third auxiliary display panel 176,fourth auxiliary display panel 182, fifth auxiliary display panel 184,sixth auxiliary display panel 186, and seventh auxiliary display panel188).

FIG. 1B depicts a high-level block diagram of a computer system forimplementing various embodiments of the present disclosure, according toembodiments. The mechanisms and apparatus of the various embodimentsdisclosed herein apply equally to any appropriate computing system. Themajor components of the computer system 100 include one or moreprocessors 102, a memory 104, a terminal interface 112, a storageinterface 114, an I/O (Input/Output) device interface 116, and a networkinterface 118, all of which are communicatively coupled, directly orindirectly, for inter-component communication via a memory bus 106, anI/O bus 108, bus interface unit 109, and an I/O bus interface unit 110.

The computer system 100 may contain one or more general-purposeprogrammable central processing units (CPUs) 102A and 102B, hereingenerically referred to as the processor 102. In embodiments, thecomputer system 100 may contain multiple processors; however, in certainembodiments, the computer system 100 may alternatively be a single CPUsystem. Each processor 102 executes instructions stored in the memory104 and may include one or more levels of on-board cache.

In embodiments, the memory 104 may include a random-access semiconductormemory, storage device, or storage medium (either volatile ornon-volatile) for storing or encoding data and programs. In certainembodiments, the memory 104 represents the entire virtual memory of thecomputer system 100, and may also include the virtual memory of othercomputer systems coupled to the computer system 100 or connected via anetwork. The memory 104 can be conceptually viewed as a singlemonolithic entity, but in other embodiments the memory 104 is a morecomplex arrangement, such as a hierarchy of caches and other memorydevices. For example, memory may exist in multiple levels of caches, andthese caches may be further divided by function, so that one cache holdsinstructions while another holds non-instruction data, which is used bythe processor or processors. Memory may be further distributed andassociated with different CPUs or sets of CPUs, as is known in any ofvarious so-called non-uniform memory access (NUMA) computerarchitectures.

The memory 104 may store all or a portion of the various programs,modules and data structures for processing data transfers as discussedherein. For instance, the memory 104 can store a display size managementapplication 150. In embodiments, the display size management application150 may include instructions or statements that execute on the processor102 or instructions or statements that are interpreted by instructionsor statements that execute on the processor 102 to carry out thefunctions as further described below. In certain embodiments, thedisplay size management application 150 is implemented in hardware viasemiconductor devices, chips, logical gates, circuits, circuit cards,and/or other physical hardware devices in lieu of, or in addition to, aprocessor-based system. In embodiments, the display size managementapplication 150 may include data in addition to instructions orstatements.

The computer system 100 may include a bus interface unit 109 to handlecommunications among the processor 102, the memory 104, a display system124, and the I/O bus interface unit 110. The I/O bus interface unit 110may be coupled with the I/O bus 108 for transferring data to and fromthe various I/O units. The I/O bus interface unit 110 communicates withmultiple I/O interface units 112, 114, 116, and 118, which are alsoknown as I/O processors (IOPs) or I/O adapters (IOAs), through the I/Obus 108. The display system 124 may include a display controller, adisplay memory, or both. The display controller may provide video,audio, or both types of data to a display device 126. The display memorymay be a dedicated memory for buffering video data. The display system124 may be coupled with a display device 126, such as a standalonedisplay screen, computer monitor, television, or a tablet or handhelddevice display. In one embodiment, the display device 126 may includeone or more speakers for rendering audio. Alternatively, one or morespeakers for rendering audio may be coupled with an I/O interface unit.In alternate embodiments, one or more of the functions provided by thedisplay system 124 may be on board an integrated circuit that alsoincludes the processor 102. In addition, one or more of the functionsprovided by the bus interface unit 109 may be on board an integratedcircuit that also includes the processor 102.

The I/O interface units support communication with a variety of storageand I/O devices. For example, the terminal interface unit 112 supportsthe attachment of one or more user I/O devices 120, which may includeuser output devices (such as a video display device, speaker, and/ortelevision set) and user input devices (such as a keyboard, mouse,keypad, touchpad, trackball, buttons, light pen, or other pointingdevice). A user may manipulate the user input devices using a userinterface, in order to provide input data and commands to the user I/Odevice 120 and the computer system 100, and may receive output data viathe user output devices. For example, a user interface may be presentedvia the user I/O device 120, such as displayed on a display device,played via a speaker, or printed via a printer.

The storage interface 114 supports the attachment of one or more diskdrives or direct access storage devices 122 (which are typicallyrotating magnetic disk drive storage devices, although they couldalternatively be other storage devices, including arrays of disk drivesconfigured to appear as a single large storage device to a hostcomputer, or solid-state drives, such as flash memory). In someembodiments, the storage device 122 may be implemented via any type ofsecondary storage device. The contents of the memory 104, or any portionthereof, may be stored to and retrieved from the storage device 122 asneeded. The I/O device interface 116 provides an interface to any ofvarious other I/O devices or devices of other types, such as printers orfax machines. The network interface 118 provides one or morecommunication paths from the computer system 100 to other digitaldevices and computer systems; these communication paths may include,e.g., one or more networks 130.

Although the computer system 100 shown in FIG. 1B illustrates aparticular bus structure providing a direct communication path among theprocessors 102, the memory 104, the bus interface 109, the displaysystem 124, and the I/O bus interface unit 110, in alternativeembodiments the computer system 100 may include different buses orcommunication paths, which may be arranged in any of various forms, suchas point-to-point links in hierarchical, star or web configurations,multiple hierarchical buses, parallel and redundant paths, or any otherappropriate type of configuration. Furthermore, while the I/O businterface unit 110 and the I/O bus 108 are shown as single respectiveunits, the computer system 100 may, in fact, contain multiple I/O businterface units 110 and/or multiple I/O buses 108. While multiple I/Ointerface units are shown, which separate the I/O bus 108 from variouscommunications paths running to the various I/O devices, in otherembodiments, some or all of the I/O devices are connected directly toone or more system I/O buses.

In various embodiments, the computer system 100 is a multi-usermainframe computer system, a single-user system, or a server computer orsimilar device that has little or no direct user interface, but receivesrequests from other computer systems (clients). In other embodiments,the computer system 100 may be implemented as a desktop computer,portable computer, laptop or notebook computer, tablet computer, pocketcomputer, telephone, smart phone, or any other suitable type ofelectronic device.

FIG. 1B depicts several major components of the computer system 100.Individual components, however, may have greater complexity thanrepresented in FIG. 1B, components other than or in addition to thoseshown in FIG. 1B may be present, and the number, type, and configurationof such components may vary. Several particular examples of additionalcomplexity or additional variations are disclosed herein; these are byway of example only and are not necessarily the only such variations.The various program components illustrated in FIG. 1B may beimplemented, in various embodiments, in a number of different manners,including using various computer applications, routines, components,programs, objects, modules, data structures, etc., which may be referredto herein as “software,” “computer programs,” or simply “programs.”

FIG. 6 is a flowchart illustrating a method 600 for display sizemanagement for an electronic display device, according to embodiments.Aspects of the disclosure relate to adjusting the display size of anelectronic display device by utilizing one or more auxiliary displaypanels of a set of auxiliary display panels. In embodiments, the set ofauxiliary display panels may be used in conjunction with a primarydisplay panel to convert the electronic display device between a first(e.g., smart-watch), second (e.g., smart-phone), and third (e.g.,tablet) display configuration that each have different display sizes.Leveraging variable screen sizes may facilitate flexibility andversatility of the electronic display device. The method 600 may beginat block 601.

In certain embodiments, the detecting, the determining, theestablishing, and other steps described herein may each occur in anautomated fashion without user intervention at block 604. Inembodiments, the detecting, the determining, the establishing, and othersteps described herein may be carried out by an internal display sizemanagement application maintained in a persistent storage device of theelectronic display device. In certain embodiments, the steps describedherein may be carried out by an external display size management modulehosted by a remote computing device or server (e.g., accessible via asubscription, usage-based, or other service model).

At block 620, a display reconfiguration request may be detected by adisplay controller of the electronic display device. Generally,detecting can include sensing, discovering, ascertaining, identifying,or otherwise receiving the display reconfiguration request. Inembodiments, the display reconfiguration request may include a command(e.g., from a user), triggering event (e.g., particular thresholdachieved), or other indication to modify the display size of theelectronic display device. As an example, in embodiments, detecting thedisplay reconfiguration request may include receiving instructions froma user of the electronic display device to increase or decrease thescreen size of the electronic display device (e.g., via a button press,dialogue box selection, setting/parameter configuration). Inembodiments, the display reconfiguration request may include a batterylife criterion (e.g., battery life below a threshold), a screenresolution criterion (e.g., recommended resolution for a particulardisplay size), or a usability criterion (e.g., larger screen size forincreased letter readability). As an example, it may be detected that aparticular display configuration (e.g., smart-watch mode) should not beused in combination with letters below a threshold font size (e.g., tofacilitate readability for a user). Accordingly, in response todetecting that characters below the threshold font size are displayed onthe electronic display device, it may be desirable to convert theelectronic display device to a larger screen size (e.g., smart-phonemode, tablet-mode) to allow for increased visibility. Other methods ofdetecting the display reconfiguration request are also possible.

In embodiments, a display controller of the electronic display devicemay sense that a battery life level of the electronic display device hasfallen below a battery life threshold at block 622. Generally, sensingcan include detecting, discovering, ascertaining, identifying, orotherwise determining that the battery life of the electronic displaydevice has fallen below the battery life threshold. For instance,sensing may include using a device manager of the electronic displaydevice to survey the usage state of various components of the electronicdisplay device, and ascertaining that the remaining battery life of theelectronic display device has fallen below a battery life threshold(e.g., 10%). In response to sensing that the battery life has fallenbelow the battery life threshold, it may be ascertained to change thedisplay configuration of the electronic display device at block 624.Generally, ascertaining can include identifying, concluding, selecting,or otherwise determining to change the display configuration of theelectronic display device. In embodiments, ascertaining to change thedisplay configuration of the electronic display device may includeselecting a display configuration that has a smaller screen size (e.g.,in order to conserve battery life). Other methods of sensing that thebattery life of the electronic display device has fallen below a batterylife threshold and ascertaining to change the display configuration ofthe electronic display device are also possible.

At block 650, a display configuration for the primary display panel andthe set of auxiliary display panels may be determined. The displayconfiguration may be determined by the display controller of theelectronic display device in response to detecting the displayconfiguration request. Generally, determining can include identifying,concluding, selecting, or otherwise ascertaining to modify, adjust,convert, or change the display configuration of the electronic displaydevice. In embodiments, determining the display configuration for theelectronic display device may be based on the detected displayreconfiguration request. For instance, in certain embodiments, thedisplay reconfiguration request may specify a desired displayconfiguration for the electronic display device. As another example,initiation or invocation of a particular application on the electronicdisplay device may trigger conversion to a particular displayconfiguration (e.g., initialization of a movie application may promptconversion to a tablet mode having a larger screen size, initializationof a phone call may prompt conversion to a smart-phone mode). Asdescribed herein, the electronic display device may be configured tooperate in one or more display configurations. In embodiments, asmart-watch mode (e.g., compact screen size, wearable design) may bedetermined for the electronic display device at block 652. Inembodiments, a smart-phone mode (e.g., one-handed usage form-factor,lightweight, pocket-size) may be determined for the electronic displaydevice at block 654. In embodiments, a tablet mode (e.g., large screensize, two-handed usage form factor) may be determined for the electronicdisplay device at block 656. Other methods of determining the displayconfiguration for the electronic display device are also possible.

At block 680, the display configuration may be established bypositioning a subset of the set of auxiliary display panels to adjustthe display size of the electronic display device. Generally,establishing can include assembling, forming, converting, instantiating,or otherwise arranging the set of auxiliary display panels to establishthe display configuration. As described herein, establishing the displayconfiguration may include configuring the set of auxiliary displaypanels to one or more of a smart-watch mode, a smart-phone mode, or atablet-mode. In embodiments, the smart-watch mode may be established atblock 682. Establishing the smart-watch mode may include maintaining theset of auxiliary display panels in a non-active state within a storagecompartment of the electronic storage device, and providing a firstdisplay arrangement that achieves a first display size threshold for theprimary display panel. In embodiments, the smart-phone mode may beestablished at block 684. Establishing the smart-phone mode may includepositioning first, second, third, and fourth auxiliary display panelsadjacent to the primary display panel (e.g., using a set of slidemounts) and providing a second display arrangement that achieves asecond display size threshold (e.g., twice the size of the first displaysize threshold). In embodiments, the tablet-mode may be established atblock 686. Establishing the tablet mode may include positioning first,second, third, and fourth auxiliary display panels adjacent to theprimary display panel, a fifth auxiliary display panel adjacent to thefirst auxiliary display panel, a sixth auxiliary display panel adjacentto the second auxiliary display panel, a seventh auxiliary display paneladjacent to the third auxiliary display panel, an eighth auxiliarydisplay panel adjacent to the fourth auxiliary display panel, andproviding a third display arrangement to the primary display panel andthe set of auxiliary display panels that achieves a third display sizethreshold (e.g., twice the size of the second display size threshold).Other methods of establishing the display configuration for theelectronic display device are also possible.

Method 600 concludes at block 699. Aspects of method 600 may provideperformance or efficiency benefits for display size management for anelectronic display device. For example, aspects of method 600 may havepositive impacts with respect to determining and establishing a displayconfiguration for the electronic display device. As described herein,the detecting, determining, and establishing described herein may eachoccur in an automated fashion without user intervention. Altogether,leveraging display size adjustment techniques may promote flexibilityand versatility for electronic display devices.

Embodiments according to this disclosure may be provided to end-usersthrough a cloud-computing infrastructure. Cloud computing generallyrefers to the provision of scalable computing resources as a serviceover a network. More formally, cloud computing may be defined as acomputing capability that provides an abstraction between the computingresource and its underlying technical architecture (e.g., servers,storage, networks), enabling convenient, on-demand network access to ashared pool of configurable computing resources that can be rapidlyprovisioned and released with minimal management effort or serviceprovider interaction. Thus, cloud computing allows a user to accessvirtual computing resources (e.g., storage, data, applications, and evencomplete virtualized computing systems) in “the cloud,” without regardfor the underlying physical systems (or locations of those systems) usedto provide the computing resources.

Typically, cloud-computing resources are provided to a user on apay-per-use basis, where users are charged only for the computingresources actually used (e.g., an amount of storage space used by a useror a number of virtualized systems instantiated by the user). A user canaccess any of the resources that reside in the cloud at any time, andfrom anywhere across the Internet. In context of the present disclosure,a user may access applications or related data available in the cloud.For example, the nodes used to create a stream computing application maybe virtual machines hosted by a cloud service provider. Doing so allowsa user to access this information from any computing system attached toa network connected to the cloud (e.g., the Internet).

Embodiments of the present disclosure may also be delivered as part of aservice engagement with a client corporation, nonprofit organization,government entity, internal organizational structure, or the like. Theseembodiments may include configuring a computer system to perform, anddeploying software, hardware, and web services that implement, some orall of the methods described herein. These embodiments may also includeanalyzing the client's operations, creating recommendations responsiveto the analysis, building systems that implement portions of therecommendations, integrating the systems into existing processes andinfrastructure, metering use of the systems, allocating expenses tousers of the systems, and billing for use of the systems.

The flowchart and block diagrams in the Figures illustrate thearchitecture, functionality, and operation of possible implementationsof systems, methods, and computer program products according to variousembodiments of the present invention. In this regard, each block in theflowchart or block diagrams may represent a module, segment, or portionof instructions, which comprises one or more executable instructions forimplementing the specified logical function(s). In some alternativeimplementations, the functions noted in the block may occur out of theorder noted in the figures. For example, two blocks shown in successionmay, in fact, be executed substantially concurrently, or the blocks maysometimes be executed in the reverse order, depending upon thefunctionality involved. It will also be noted that each block of theblock diagrams and/or flowchart illustration, and combinations of blocksin the block diagrams and/or flowchart illustration, can be implementedby special purpose hardware-based systems that perform the specifiedfunctions or acts or carry out combinations of special purpose hardwareand computer instructions.
